When optical systems demand precision, reliability, and performance, a well-engineered optical assembly is key. At Knight Optical, we specialise in providing custom optical assemblies that bring together expertly designed optical elements, mechanical housings, and precision coatings, all built to meet the most demanding specifications.

What Is an Optical Assembly?

An optical assembly consists of two or more optical components that work together to perform a specific optical function such as focusing, imaging, or beam manipulation. These can include combinations of lenses, prisms, beamsplitters, mirrors, or filters, all carefully aligned within a mechanical structure.

Typical examples include:

• Beam expanders for laser and optical communication systems
• Imaging lenses for cameras, vision systems, and scientific instruments
• Eyepiece and objective lenses used in microscopes, telescopes, and optical instruments
• Spectrometer optics designed for precise wavelength analysis and measurement
